Essay Assignment 2: Sensation and Perception of Schizophrenia

Generally a diagnosed person with Schizophrenia in basis of the latest edition of DSM is when Two (or more) of the following, each present for a significant portion of time during a 1-month period or less if successfully treated. First are delusions, where false beliefs are strongly held in spite of invalidating evidence. Merely having such belief proves how much this type patient of is experiencing a lack proper perceptual image and view of the actual world. That’s why a person with Schizophrenia could be described as “Losing in touch with reality”, having their own improbable perception of what they are experiencing that are entirely different from a normal person. Either perceiving heightened feelings of anxiousness or beliefs in grandeur in reference to themselves or their environment. Next are hallucinations, a key factor to explain how much diagnosed Schizophrenics are impaired with sensational and perceptual concept of what they encounter in connection with a person’s five senses. Visually, seeing things that are not there or that other people cannot see. Auditory, hearing voices that other people can’t hear. Tactile, feeling things that other people cannot smell, or not smelling the same thing that other people do smell. Gustatory experiences, tasting things that aren’t there. With this, a lot of studies are made solely for the purpose of proving such claims. In terms of their visual abilities, Elahipanah, A., Christensesn, BK and Reignold, E.M. found a significant impairment in patients’ visual search performance was only evident when targets were more eccentric and their performance was more similar to healthy controls when the target was located closer to the center of the search display. These results support the hypothesis that a narrower visual span may underlie impaired visual search performance among patients with schizophrenia. In line with visual search, it implies the spotlight

    The Faces Interactive website lets us take a look at what it really means to be diagnosed with schizophrenia, instead of the many misinterpreted beliefs that are associated with this disorder. Under the Diagnostic Overview tab, it is explained that this disorder has positive and negative symptoms. As mentioned in under the tab, the two most common positive symptoms include Delusions and Hallucinations. Often times, we might confuse the two, but they each hold very different definitions. Faces Interactive defines Delusions as, “… a firmly held believe that is not grounded in reality” (McGrawHill Higher Education, 2007, Diagnostic Overview). There are many forms of delusions including delusions of persecution, delusions of reference, and delusions of grandeur. Faces Interactive gives applicable examples that differentiate between the three, “Valerie has expressed a range of delusions including delusions of persecution – that people were plotting to hurt she and her family, delusions of…

This inaccurate interpretation of reality can distort the way a person expresses their emotions, thinks, acts, and communicates to others. This can take a severe toll on their daily lives raising their risk for developing problems when dealing with work, relationships, and school. There are many different types and degrees of severity of schizophrenia. Some people will only experience one psychotic episode in their entire lifetime, while others can have episodes on a much more frequent basis. The types of schizophrenia can range from paranoid, disorganized, catatonic, undifferentiated, and residual schizophrenia.…

    The cognitive approach acknowledges the role of biological factors. Frith 92 found a disconnection between frontal areas of the brain concerned with action and the posterior areas of the brain that control perception, explaining auditory hallucinations. This causes a split from reality where sz are unable to distinguish between actions brought by external forces and those generated internally this then causes the positive symptoms of sz e.g. auditory hallucinations, delusions and lack of self-mentoring. Hemsley 93 suggests that sz don’t know how to distinguish between different information therefore they become overloaded with sensory information.…

    Schizophrenia one of the more common psychological disorders, also called mental illnesses. Schizophrenia affects behavior as well as thoughts, and encompasses many different things, including auditory hallucinations and mood swings. At some point this disorder may even manifest itself into a psychotic phase that involves delusions and disorganized speech along with bizarre behavior. People who have schizophrenia believe that the hallucinations are real, and even if they don’t believe that the hallucination is real, it seems real. The way that schizophrenia manifests itself is different from person to person. Some people can manage to live life fully independently with schizophrenia, and with medication can keep it under control. However, other people may never be able to function fully, and will not be able to live on their own due to the delusions and hallucinations. In severe progressions of this disorder, people lose the ability to keep in touch with reality, and become paranoid and anti-social, while often being petrified of the hallucinations that they live with.…

    “Schizophrenia is characterized by a constellation of distinctive and predictable symptoms. The symptoms that are most commonly associated with the disease are called positive symptoms, which denote the presence of grossly abnormal behavior. These include thought disorder, delusions, and hallucinations. Thought disorder is the diminished ability to think clearly and logically. Often it is manifested by disconnected and nonsensical language that renders the person with schizophrenia incapable of participating in conversation, contributing to his alienation from his family, friends, and society. Delusions are common among individuals with schizophrenia. An affected person may believe that he is being conspired against. Hallucinations can be heard, seen, or even felt; most often they take the form of voices heard only by the afflicted person,” (http://www.schizophrenia.com). While these symptoms are obvious, consistent, and usually expected from those affected by schizophrenia, there are also “quieter indications” known as “negative symptoms,” that may contribute to the gravity of the illness. The quieter symptoms are responsible for the absence of “normal” behavior. In other words, people might have a dull or flattened reaction to things, people, and situations; they often show lack of emotions and other physical expressions. They might also act and feel indifferent, becoming more and more socially…

    Schizophrenia is a brain disorder which can affect a person’s mental well-being. Suffering from schizophrenia can terrify people and make them withdrawn from family and friends or make them extremely agitated. Some people with the disorder are known to hear voices, believe people are trying to harm them or are reading their minds. The exact cause is unknown, however many scientists believe that genes and environment both play a role together. Within the brain, the level of dopamine and glutamine, both chemical messengers, may be out of balance. Another cause may come from the brain structure being slightly abnormal. For example this brain scan (see figure 1) of identical twins show that the brain on the left has much larger/fluid filled ventricles which is common for schizophrenic patients, compared with the twin that does not have the illness on the right.
